Description

Technical Field

[0001] The utility model belongs to the technical field of mining equipment, and specifically relates to a buffer feeding device. Background Art

[0002] At present, cone crushers, as ore crushing equipment in mines, are increasingly favored by ore dressing plants due to their large processing capacity, low failure rate, and low energy consumption. The main structure of a cone crusher includes a feed hopper, an upper frame, a moving cone, a machine base, a discharge hopper, a transmission shaft, a V-belt, a motor, etc., and auxiliary devices include a hydraulic lubrication station, an electric control cabinet, etc. When working, the motor drives the eccentric sleeve to rotate through the V-belt, the transmission shaft, and the transmission gear. The moving cone performs a pendulum motion under the action of the eccentric sleeve, causing the moving cone and the fixed cone to sometimes approach and sometimes deviate. The material is continuously squeezed and impacted in the crushing chamber and crushed, and the crushed material is discharged from the bottom.

[0025] like Figure 1 and Figure 3 As shown, in one embodiment of the utility model, a buffer feeding device is provided. Specifically, the buffer feeding device is applied to a cone crusher, and includes a cylinder 1, a receiving bin and a power assembly. The cylinder 1 is cylindrical and is installed at the feed port of the cone crusher when in use; the receiving bin is rotatably installed on the cylinder 1, and the axis coincides with the axis of the cylinder 1 during rotation; the power assembly is installed on the cylinder 1 and is connected to the receiving bin to drive the receiving bin to rotate. A receiving port 3 is provided at the top of the receiving bin, and the receiving port 3 is used to receive the material to be received; a discharge port is provided at the bottom of the receiving bin, and the discharge port is used to discharge the material to the feed port of the cone crusher.

[0026] The buffer feeding device of this embodiment is installed at the feed port of the cone crusher, receives materials (such as ore to be crushed) from the belt conveyor, and then transports them to the cone crusher from the feed port of the cone crusher, which can play a buffering role and solve the problem of reduced crushing efficiency of the cone crusher due to large impact force, unevenness and discontinuity when the belt conveyor feeds ore. At the same time, the receiving bin of the buffer feeding device can rotate under the drive of the power component, the degree of automation is improved, and the discharge port can feed 360° uniformly in the crushing chamber of the cone crusher, solving the problem of uneven feeding of the cone crusher, ensuring efficient and full-load operation of the cone crusher, improving the working efficiency of the cone crusher, and reducing the failure rate. It has great market competitiveness, huge market space and promotion prospects, and significant economic benefits.

[0027] like Figure 2 and Figure 3As shown, in one embodiment of the utility model, the receiving bin includes a receiving hopper portion 9 and a material distribution chute portion 6. The receiving hopper portion 9 is cylindrical, and a receiving port 3 is provided at the top of the receiving hopper portion 9. The receiving hopper portion 9 can receive and temporarily store ore from the belt conveyor when in use, and can play a buffering role when the ore feeding amount of the belt conveyor suddenly increases. The material distribution chute portion 6 is connected to the receiving hopper portion 9 at the bottom end of the receiving hopper portion 9, and the bottom end of the material distribution chute portion 6 is a discharge port. The ore in the receiving hopper portion 9 can be discharged into the cone crusher through the discharge port at the bottom end of the material distribution chute portion 6.

[0028] Furthermore, in this embodiment, the receiving port 3 is expanded to facilitate the entry of ore. The top height of the receiving port 3 is higher than the top height of the cylinder 1. When the top of the receiving hopper 9 is expanded, the ore can be easily entered into the receiving hopper 9.

[0029] like Figure 3 As shown, in one embodiment of the utility model, the receiving bin further includes a receiving neck 8, the upper end of the receiving neck 8 is connected to the receiving port 3, and the lower end is connected to the receiving hopper 9, which is used as a passage for the ore to enter the receiving hopper 9. Preferably, the radial inner diameter of the receiving neck 8 is smaller than the radial inner diameter of the receiving hopper 9. During operation, when the ore enters normally, it enters the receiving neck 8 from the receiving port 3, then enters the receiving hopper 9, and finally is discharged into the cone crusher from the discharge port of the material distribution chute 6. If the amount of ore suddenly increases, the ore can stay in the receiving hopper 9 for a short time, thereby ensuring the stability of the feeding of the cone crusher.

[0030] Furthermore, in the present embodiment, the receiving bin further comprises a protective wall 10, which is in the shape of a circular ring and concentrically surrounds the outer side of the receiving neck 8, and is provided with a gap between the receiving neck 8. In the present embodiment, the receiving bin is connected to the cylinder 1 via the protective wall 10, and there is a gap between the protective wall 10 and the receiving neck 8, which can avoid the impact of the ore colliding with the receiving neck 8 on the connection between the receiving bin and the cylinder 1, especially reducing the impact on the power assembly. Preferably, the top of the protective wall 10 is sealed with the receiving port 3, and the cylinder 1, the protective wall 10, and the receiving port 3 are closed at the top by a steel plate, which can prevent the ore from entering the gap between the protective wall 10 and the receiving neck 8, and prevent the ore from entering the gap between the protective wall 10 and the cylinder 1.

[0031] like Figure 1 and Figure 3As shown, in one embodiment of the utility model, the material distribution chute portion 6 is enclosed by a first side plate, a second side plate, a third side plate and a fourth side plate in sequence. The cross section of the material distribution chute portion 6 in the direction perpendicular to the axis of the receiving hopper portion 9 is rectangular. From inside to outside along the radial direction of the receiving hopper portion 9, the first side plate is located on the inner side of the third side plate, and the second side plate, the third side plate and the fourth side plate are all arranged along the axis of the receiving hopper portion 9. The first side plate is arranged at an angle, gradually facing the third side plate from top to bottom along the axis of the receiving hopper portion 9, and the inclination angle ranges from 30° to 60°, for example, it can be 30°, 35°, 40°, 45°, 50°, 55°, 60°, or any intermediate value between any two adjacent endpoint values ​​mentioned above. In the present embodiment, along the axis of the receiving hopper portion 9 from top to bottom, the material distribution chute portion 6 is closed, which can play a certain blocking role on the ore, reduce the kinetic energy of the ore when it falls, and further reduce the load on the cone crusher caused by the ore hitting the cone crusher. Preferably, the inclination angle of the first side plate is 45°, which can also take into account the smoothness of the discharge. It is worth noting that in the present embodiment, in order to facilitate the description of the introduction of the first side plate, the second side plate, the third side plate and the fourth side plate, in actual manufacturing, the second side plate, the third side plate and the fourth side plate can be formed by bending a piece of steel plate to form the second side plate, the third side plate and the fourth side plate connected to each other, and then connected to the first side plate by full welding.

[0032] Furthermore, in this embodiment, there are multiple material distribution chute parts 6, and the multiple material distribution chute parts 6 are distributed in a circular array below the receiving hopper part 9, which can accelerate the falling of the ore. Preferably, the number of the material distribution chute parts 6 is two, and the two material distribution chute parts 6 are symmetrically arranged, which can symmetrically distribute the ore into the crushing chamber of the cone crusher.

[0033] like Figure 3 As shown, in one embodiment of the utility model, a first bearing seat 11, a second bearing seat 13 and a supporting bearing 12 are installed between the receiving bin and the cylinder 1. Specifically, the first bearing seat 11 is concentrically installed on the outer side of the circumference of the protective wall 10 of the receiving bin, and the second bearing seat 13 is concentrically installed on the cylinder 1. The top of the supporting bearing 12 abuts against the first bearing seat 11, and the bottom abuts against the second bearing seat 13. In this embodiment, by arranging the first bearing seat 11, the second bearing seat 13 and the supporting bearing 12 between the receiving bin and the protective wall 10, the receiving bin can be mounted on the cylinder 1, so that the receiving bin can rotate freely along its own axis. Optionally, the supporting bearing 12 is a ball slewing bearing 12, which can make the receiving bin rotate more smoothly during operation.

[0034] like Figure 3As shown, in one embodiment of the utility model, the power assembly includes a driving motor 5, a reducer 4, a large gear 7 and a small gear. Among them, the driving motor 5 and the reducer 4 are both installed on the cylinder 1, and the driving motor 5 is connected to the reducer 4; the large gear 7 is installed on the outside of the receiving bin, and the axis of the large gear 7 coincides with the axis of the receiving bin; the small gear is connected to the reducer 4 and meshes with the large gear 7. During operation, the driving motor 5 drives the receiving bin to rotate through the reducer 4 and the gear meshing transmission. Preferably, the driving motor 5 is a variable frequency motor, which can adjust the speed of the receiving bin.

[0035] like Figure 1 and Figure 2 As shown, in one embodiment of the utility model, a radar level meter 2 is provided on the upper part of the receiving bin, which can measure the material height in the receiving bin, and thus timely grasp the operating status of the cone crusher.

[0036] In one embodiment of the utility model, a protective plate layer is provided on the inner surface of the receiving bin, which can improve the anti-collision ability and wear resistance of the receiving bin, thereby increasing the service life of the receiving bin. As an implementable embodiment, the protective plate layer is covered with a high manganese steel plate.
